In scientific research related to life sciences, the two terms cell strain and cell line are often heard. For many students who are new to the field, these terms are often confusing. In this issue, we will briefly introduce the differences and connections between these two terms.Hela cell strainOrig

In recent years, questions related to PCR (Polymerase Chain Reaction) technology have frequently appeared in the biology section of China's Gaokao (college entrance exam). These questions may ask students to explain the principles of PCR or analyze its role in specific application scenarios. Such qu

Cell culture, also known as cell cloning technology, refers to the growth of cells under in vitro conditions. During culture, cells no longer form tissues; instead, the culture consists of individual cells or cell clusters. Since cultured cells live in an artificial environment, they may be affected

Contamination in cell culture is one of the most common problems encountered in cell culture laboratories and can sometimes lead to serious consequences. Contaminants in cell culture can be divided into two major categories: l Chemical contaminants, such as impurities in media, serum, and water, end

01 Light IntensityLight intensity plays a significant role in the proliferation of cultured cells and the differentiation of organs. Current studies show that light intensity has a noticeable effect on the initial division of explants and cells. Generally, strong light intensity results in sturdy se

I. Microbial CultureMicrobial culture refers to the artificial growth and reproduction of specific microorganisms by using prepared culture media and controlled conditions (such as temperature). It includes the culture of bacteria, molds, and yeast. These microorganisms typically have very short lif
